Aircast AirSport Ankle Brace: The original step-in for mild sprains. Get proven protection with the easy 'Step in, Strap Up, and Go!' design and core Aircell technology.
The Aircast AirSport Ankle Brace is the original, time-tested choice for athletes seeking reliable, step-in protection against mild to moderate ankle sprains (Grade I/II) and chronic instability. Positioned as the premier value option, the AirSport delivers the superior semi-rigid support Aircast is known for, without the premium cost of advanced lacing systems. It is the perfect daily training and game-day support for athletes who need stabilization without sacrificing speed or agility.
Core Features & Mild-Sprain Technology
The effectiveness of the Aircast AirSport lies in its clinically proven combination of materials and stabilization technology:
-
Semi-Rigid Stirrup Shells: Encased in foam, these anatomically designed shells provide foundational protection against inversion and eversion forces (ankle rolling), critical for preventing sprain recurrence.
-
Aircell Cushioning: The foam-filled aircells compress the joint, reducing swelling and providing a custom, comfortable fit that molds to the ankle's contours.
-
ATF Cross-Strap: This critical feature works similarly to athletic tape, directly addressing the Anterior Talofibular (ATF) ligament—the most commonly injured ligament in ankle sprains—by locking the heel in place and limiting anterior drawer movement.
-
True Step-In Design: Unlike time-consuming lace-up braces, the AirSport features a simple posterior step-in system and an automatic heel adjustment, making application fast, easy, and hassle-free, which is essential for quick application during training or competition.
-
Low Profile & Lightweight: Built with strong, coated fabric, the brace fits effortlessly into most athletic footwear (running shoes, cleats, basketball shoes) without adding significant bulk.
-
Universal fit - Fits left or right foot; available in multiple sizes. See Size & Fit tab for sizing chart and measurement/fit help.
